具有类型化条件查询的XML映射

I'm using hibernate with xml mapping I'm trying to run some simple code without much success. I am confident that mapping and classes are correct as I am able to perform other queries using JPQL.

我正在使用hibernate和xml映射我试图运行一些简单的代码而没有太大的成功。我确信映射和类是正确的,因为我能够使用JPQL执行其他查询。

This is a snippet of my code:

这是我的代码片段:

CriteriaBuilder qb = em.getCriteriaBuilder();
CriteriaQuery<Report> myquery = qb.createQuery(Report.class);
Root<Report> report = myquery.from(Report.class);
List<Report> result = em.createQuery(myquery).getResultList();

And this is the Stack:

这是堆栈:

Exception in thread "main" java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: unexpected token: null near line 1, column 29 [select generatedAlias0 from null as generatedAlias0] 
...
...
Caused by: org.hibernate.hql.ast.QuerySyntaxException: unexpected token: null near line 1, column 29 [select generatedAlias0 from null as generatedAlias0]
...
...

Any suggestion? Thanks!

有什么建议吗?谢谢!
